Arsenal have reportedly made an offer to Borussia Dortmund for Pierre-Emerick Aubameyang.

The Gunners are hopeful of completing a deal for the Gabon striker as a replacement for Alexis Sanchez.

Aubameyang was not involved as Dortmund drew with Hertha Berlin on Friday night and it had been suggested his agent would travel to London this weekend for talks.

Arsenal have held talks with Dortmund and have tabled their first official bid for the player.

Kicker claim the bid is in the region of €50m, although Dortmund are likely to want more.

Nevertheless, the deal is edging closer and Arsenal are confident of getting it done.

Dortmund chief Hans-Joachim Watzke said: "I can confirm that there has been a first request from Arsenal for Pierre-Emerick Aubameyang. We are not commenting on the sums that have been called from England since noon today."

They are also closing in on a deal for Henrikh Mkhitaryan, with Alexis Sanchez moving to Manchester United.
